Abstract

A rope driving mechanism is composed of two rope wheels and an endless rope. Said rope has nodes on it. Said rope wheel has the stambling blocks for driving the rope. Its advantages are high drive efficiency for ultrahigh-power drive, simple structure and very low cost.

Description

Rope transmission mechanism

Affiliated technical field

The present invention relates to mechanical transmission mechanism, especially close the rope transmission mechanism that forms by rope sheave and knot.

Background technique

Present known the most frequently used driving mechanism has to include is with transmission and chaindriven disturbing property transmission and gear transmission.Though this two classes transmission is contributed remarkable, also there is deficiency separately in machine-building: gear transmission cost height, the lubricating requirement height, noise is big, is not suitable for transmitting superhigh power, or says that cost is high when transmitting superhigh power.The velocity ratio of band transmission is inaccurate, is unsuitable for high temperature and the environment of the medium that is corrosive.The life-span of band is short.Chain-driven lubricating requirement height, noise are big, the cost height of chain.

Summary of the invention

The driving mechanism that the purpose of this invention is to provide that a kind of structure is more economized, cost is lower, suitable environment and transmitted power are wider, be easy to install, do not need substantially to lubricate, noise is low, the life-span is long.

For achieving the above object, the present invention has adopted rope transmission mechanism, is made of jointly rope sheave and rope, and the outer rim of rope sheave is provided with more than one button and stumbles; Described rope is made of more than one nothing joint rope and the fake that has the joint rope to form.

Be installed on the rope sheave outer rim button by the button frame, buckle axle and kink in buckle on the axle also alive insert in buckle within the frame, the top is provided with recess and the bolt of buckleing of elastic element constitutes jointly.

Be installed in that flat board that stumbling on the rope sheave outer rim form by more than one the flat board by being provided with recess is stumbled and many of being formed by stake more than three stumble and constitute.

Be installed in joint on the rope by more than one directly be enclosed within on the rope by the through hole pearl, and fixing fixed knot and buckle the active section that the pin that forms with bolt is connected to form by joint cover, the joint on two tops that are installed in rope respectively and constitute.

When needs improved the constancy of velocity ratio, available individual thread substituted the rope that is twisted into by multi-filament.

But owing to installing tache on the rope sheave outer rim, also can install and stumble, and button have multiple spot (a plurality of fastening point) button and single-point (single fastening point) button minute, stumbling also has flat board to stumble and many branches of stumbling, rope has joint rope and the branch that does not have the joint rope, joint has the branch of fixed knot and active section, rope sheave has the branch of driving wheel and follower again, so rope transmission mechanism has the multiple combination that is fit to different needs.For example: when flat board all being installed on the outer rim of driving wheel and follower stumbling, rope is gone up and should be established the rope joint accordingly, and pitch should be stumbled apart from equating with minimum; When all establishing button on driving wheel and the follower, rope should be established does not have the joint rope; The equidistant button (being preferably the single-point button) of establishing is established flat board and is stumbled on the driving wheel on the follower, when equidistantly or equidistantly not saving on a small quantity on the rope, can form the reducing gear of exporting intermittent movement.Also can carry out multiple combination and so on.

The invention has the beneficial effects as follows: constitute traction element rope valency in the rope transmission mechanism far below band, more be lower than chain, and the life-span is long, rope sheave is simple in structure, and the requirement of wheel body material is low, and the processing cost of rope sheave is also low.The rope sheave transmission almost need not to lubricate, and noise is low, and when rope was metal matter, its working environment was more than band, chain and gear drive wide adaptability.Rope easy for installation, rope transmission mechanism can extensively substitute band, chain-driven and gear transmission, more shows its impayable superiority when especially transmitting power between major diameter wheel or the tube and several tons, tens of transmission, hundreds of ton power.Rope transmission mechanism can also save speed reducer when being combined into slowing-down structure.

Embodiment

Referring to figs. 1 through Figure 19, do not stumble 4 on the outer rim of rope sheave 1 with wheel 1 button that installs 2, flat board, rope 3 tensionings that form circle are placed on the two-wheeled 1.Button (contrast Fig. 6 or Figure 15) when button 5 is restricted for not fastening, button 2 is installed by clamping bolt 7 and wheel 1.Button bolt 9 kinks are on button axle 6, and alive inserting in the button frame 8.Rope 3 is put 11 fastenings by fastening (has two fastening points 11, so claim the multiple spot button on Fig. 4; A fastening point 11 is arranged, so claim the single-point button on Figure 12), be formed with rope recess 12 between button bolt 9 and the button frame 8, flat board stumble 4 and many stumble and mistake rope recess 12 accordingly also arranged on 14.Flat board is stumbled and mainly was fit to have joint rope, stumbles for many 14 mainly to be fit to not have the joint rope.If but arrange proper, above-mentioned be fit to cross rope also can be opposite.

When button 2 was in button 5 states, the front end of button bolt 9 lifted (see figure 6) under elastic element 10 is elected, and recess 12 is flared to rope 3 states that are easy to enter that make, after rope 3 enters recess 12, the tension force of rope 3 descends the front end of button bolt 9, makes fastening put 11 buckling ropes 3, to realize the transmission between the two-wheeled 1.The structural principle of single-point button and multiple spot button are restricted but be more conducive to joint together.

With reference to Figure 20, Figure 21, Figure 22, bolt shape pin 17 on the active section is buckled 16 backs by joint and is tightened with joint cover 15, because the shaft part of pin 17 is conical, therefore when pin 17 is screwed into joint cover 15 initial, joint button 16 does not put in place fully, along with constantly being screwed into of pin 17, also constantly displacement of joint button 16.The conical design of shaft part is convenient to pin 17 pinnings joint cover 15 and buckle 16 with joint on the pin 17, makes easier being installed to of the rope 3 that has movable joint take turns 1 and get on.

When reality was implemented, each button axle 6 also should be designed to pin 17 shapes.Restricting 3 when installing on the wheel 1 that is provided with sling 2, unclamp the button axle of respectively detaining on 26 earlier, will restrict 3 installs, and then tightens each button axle 6, makes each fastening point 11 on the button 2 rope 3 that links closely, thereby makes rope 3 acquisition tension forces.

The working procedure of the present invention when being the retarded motion structure: being provided with on the joint rope has a joint, many buttons are arranged on the driving wheel, have flat board to stumble on the follower, do not have the joint rope because button can fasten, driving wheel makes the continuous motion of rope average rate, and stumble and can only be driven by joint, therefore, when one of joint driving is stumbled, follower rotates, joint leaves follower stall when stumbling, and the driving next time of skidding on follower to joint of restricting is stumbled, thereby makes intermittently retarded motion (can save speed reducer) of follower output.Intermittent movement all has extensive use in food processing and chemical industry, also alternative Geneva mechanism, and also more simple.

If in when design, the surface away from the wheel outer rim is brought up on the base of the recess that flat board is stumbled, and rope has strengthened rope and stumbled the friction of upper notch, thereby stumbled also can drive and do not have the joint rope just becoming the warpage state when stumbling.
